A man builds a house, displaced by heavy floods for almost a year, while taking refuge at a camp in Charsadda, located in Pakistan's Khyber Pakhtunkhwa province July 19, 2011. Up to five million people in Pakistan are at risk from floods this year, partly due to poor reconstruction and the inadequate rehabilitation of survivors who are still reeling from last year's epic deluge, the United Nations said.
